Gillian Anderson led the congratulations for Jodie Whittaker after the actress was unveiled as the first-ever female "Doctor Who."

The "Attack the Block" star's big reveal came in the form of a much-anticipated BBC ad following the network's coverage of the Wimbledon men's final. And following the announcement, a host of famous faces took to social media to praise the former Broadchurch actress' casting in the role.

Sharing a link to a story about the new Doctor, "The Fall" star Gillian wrote: "Yes! #breakthemold (sic) #13thDoctor."

"Star Wars" actor John Boyega, who starred alongside Jodie in "Attack the Block," tweeted, "So proud of Jodie Whittaker. She's going to be awesome !!!" while The Night Of star Riz Ahmed wrote, "Jodie Whittaker is an incredible actress, an amazing person, and I'm so glad she's the new #DoctorWho."

However, not everyone was happy with the casting, with "The Avengers" writer and director Joss Whedon commenting: "I'm absolutely for progress and inclusiveness but it is fair to worry when almost every ep of Doctor Who revolved around his big ol' [redacted]."

But Jodie did her utmost to silence her critics when she gave her first interview after her casting announcement, urging fans "not to be scared by my gender".

"This is a really exciting time, and Doctor Who represents everything that's exciting about change," she told the BBC. "It feels completely overwhelming, as a feminist, as a woman, as an actor, as a human, as someone who wants to continually push themselves and challenge themselves, and not be boxed in by what you're told you can and can’t be. It feels incredible."
